JOHN METZLER, OF HERKIMER, NEW YORK.

TYPE-WRITER CABINET.

Specification of Letters Patent.

Application filed. August 22, 1907.

Patented Oct. 20, 1808.

Serial No. 389,604.

To all whom it may concern:

Be it known that 1, JOHN METZLER, a citizen of the United States, residing at Herkimer, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type-VVriter Cabinets, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved typewriter cabinet, and I declare that the following is a full, clear, concise and exact description thereof, suflicient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like letters and numerals refer to like parts throughout.

My invention consists of a typewriter cabinet which embodies a lid or cover, which, in closed position, forms a flat-top to the desk or cabinet, a platform or shelf for the support of the typewriter which is lowered into the well of the desk automatically and simultaneously with the closing of the lid and is raised into a horizontal position for use, when the lid is opened, and simple and effective means for positioning the said typewriter platform or shelf in a horizontal elevation suitable to the needs of the operator without the necessity of any adjustment of nuts, screws or bolts or the like, or of using any tools, the positioning of the typewriter platform in the desired elevation being effected by a convenient and simple manipulation of the supports of the platform as will be understood from the following description and claims when taken in connection with the accompanying drawings.

In the drawings Figure 1 represents a central vertical cross-sectional view of a typewriter desk or cabinet of the character de scribed, with the cover or lid open and the typewriter platform raised into a horizontal position ready for use by the operator. Fig. 2 re resents a cross-sectional view the same as ig. 1, but with the lid or cover closed and the typewriter latform lowered into the well or recess in t e central part of the desk or cabinet. Fig. 3 represents an enlarged side View of one of the supports of the typewriter platform in the same position if; shown in Fig. 1. Fig. 4 is an end view of Referring to the drawings in detail, A is the cabinet, B the swinging cover, C the fixed cover of the cabinet and D the swinging platform or shelf for the machine. A link L is pivoted to the cabinet at K and to the cover B, near its rearward edge, at R.

P is a fixed cleat or projection to support the cover when the cabinet is open.

H is a lever pivoted to the cover near. its forward edge, at S, the lever being pivoted at I to the cabinet or case.

H is a link pivoted to the free end J of lever H, its other end being pivoted to the shelf or platform D, near its forward edge, at

F is a cleat or bracket secured to the side of the case, one on each side. The bracket has an elevated or raised portion E in which is a slot 0, having lateral inlets M, and N.

E is an arm fixed at one end to the shelf or platform D and at the other end having a stud G to travel in slot 0 and headed to hold the arm therein.

X is a casing at the lower part of the desk against which the shelf D rests when the cabinet is closed making the well substantially dust-proof. The casing is held at its forward end to the cabinet by links X slotted for thumb-screws r whereby it may be fixed in close adjustment to the shelf D when down.

In 0 ening and closing the cabinet the cover swings on link L and lever H from one position. to the other, as shown in Figs. 1 and 2. The shelf D swings on the arm E, which is supported b stud G in one of the inlets of the bracket its movement being controlled by link 11, one end of which travels in an arc described on point I by radius IJ, its other end traveling in an are described by radius G-T on point G. The desk or cabinet being closed, the operator raises the front of the cover and presses it backward when it takes the osition shown in Fig. 1. That movement 0 the cover has swung the point J of the lever H from the place shown in Fig. 2 to that shown in Fig. 1, which has swung the shelf on its fulcrum stud G into horizontal position as seen in that figure. The various parts of the device, and their adjustment, are such that the shelf will lie in a perfectly horizontal plane in a given location of the studs G in the inlets of the bracket.

When the cabinet is closed, as in Fig. 2 the operator may change the height of that plane by pushing the arms E back and putting the studs G in some other inlet, the latter being, of course, arranged in pairs, each of a pair shelf up.

being opposite the other. These inlets, thus arranged in pairs are a given distance above or below those of the other pairs. The change of position of stud G will raise or lower that fulcrum point vertically a given,

distance. The Weight of the shelf (and machine) will tend to tip the front edge of the The upward movement of the point T will be in an are described on point J with radius JT. At the same time the point T must lie in an are described by radius GT on point G in one of its positions, and the radial distance between these several latter arcs must be the distance between the respective inlets on which the arc is drawn.

any of its positions lies nearly enough in the horizontal plane for all practical purposes.

I consider the support E and its accessory F the principal feature of my invention, but I do not'intend to limit my invention to the exact form of construction shown, as the same result may be accomplished by the em ployment of the same combination of mechanical equivalents of different form.

Having described my invention, what I claim-*asnew and desire to secure by Letters Patent, is:

1. In combination, a desk, 2. cover and a shelf swingably and connectedly mounted therein to be reciprocally raised and lowered, arms forming the pivotal support for said frame of the desk, jointed members pivotally secured at one end to the cover and atthe other end to the platform and pivotally secured near their center b0 the frame of the desk, supporting arms rigidly secured at their upper ends to the platform, supports for the said sup orting-arms rigidly secured to the frame 0 the desk and having substantially vertical slots with recesses vertically spaced therein in any opposite pair of .l

which recesses the said sup orting arms are pivotally seated, substantia ly as described.

3. In a desk, the combination of a cover and platform, means for reciprocally raising and lowering the said cover and platform,

said means including supporting arms for said platform pivotally seated in supports on the desk, said supports for said arms having slots recessed at different elevations for pivotally seating the lower ends of said arms, substantially as described.

In testimony whereof I afIiX my signature in presence of two witnesses.

JOHN METZLER.
